Select the Boot Device

The Boot Option Priority list contents depend on the BIOS boot mode that
is selected. If UEFI boot mode is selected, only UEFI boot candidates are
initialized and displayed in the Boot Option Priority list. If Legacy BIOS Mode
is selected, only Legacy BIOS boot candidates are initialized and displayed in the
Boot Option Priority list.

In addition to using the F2 key to view or edit the
system BIOS settings (see Verify BIOS Factory Default Settings), you can use the F8 key during the BIOS
startup to specify a temporary boot device. This selected boot device is in
effect only for the current system boot. The permanent boot device specified using
the F2 key will be in effect after the system boots from the
temporary boot device.

Reset or power on the server.

Select one of the following methods.

From the local server -- Press the Power button on the front panel of the server
to power off the server, then press the Power button again to power
on the server.

Press the F8 key (or Ctrl+P from a serial connection) when prompted while
the BIOS is running the power-on self-test (POST).

The Please Select Boot Device dialog box is displayed.

Select the boot device option that is appropriate to the installed operating system
and the BIOS boot mode selected, then press Enter.

Use the up and down arrows to select the boot device.

Depending on the boot mode you have selected (UEFI boot mode or Legacy
BIOS boot mode), the Please Select Boot Device dialog displays only the applicable
boot devices. For example, when the UEFI Boot Mode is elected, only UEFI
boot devices are displayed.
